Smart EV Charger Installation in the Chilterns
A smart EV charger lets you schedule when your car charges, so it draws power automatically during off-peak hours when electricity is cheapest. We install Hypervolt, Ohme and Zappi smart chargers for homeowners across the Chilterns. Every installation starts with a free in-person site survey. Our NAPIT-registered engineers handle the full job from cable route to commissioning. Call 01494 977298 to book your survey.
What is a smart EV charger and how does it save you money?
A smart EV charger connects to your home Wi-Fi and lets you control charging from an app. The real benefit is scheduling: set the charger to run between midnight and 5am and you pay substantially less per charge on tariffs like Octopus Intelligent or Octopus Go. For a typical family car covering average mileage, the difference between charging at peak rates versus off-peak can be £200 to £400 per year.
How does off-peak EV charging work with a smart charger?
On a time-of-use tariff, your energy supplier charges different rates depending on the time of day. Off-peak windows, usually between midnight and 5am, can cost as little as 7p to 10p per kWh, compared to 24p to 30p during peak hours. A smart charger integrates directly with these tariffs. You plug in when you get home, and the charger handles the rest. No manual scheduling needed on most setups.

Which smart charger brands do we install across the Chilterns?
We install three OZEV-approved smart charger brands:
- Hypervolt: British-made, solid build quality, excellent app. Works well with most smart tariffs.
- Ohme: Best-in-class smart tariff integration, particularly with Octopus. Charges automatically when rates drop without any manual scheduling.
- Zappi: Designed for solar panel integration. If you have or plan to add solar, the Zappi can prioritise cheap solar-generated electricity before pulling from the grid.
During your site survey, we discuss your car, your tariff, and your parking setup to recommend the right unit.
What does a smart EV charger installation in the Chilterns involve?
We start with a free in-person site survey. One of our NAPIT-registered engineers visits your property, checks your consumer unit, plans the cable route, and confirms the right charger for your car and home setup. On installation day, we run the cable, mount and connect the charger, set it up on the app, and test everything before we leave. Most jobs take half a day to a full day. We leave you with a certificate and full commissioning confirmation.
Why choose Chiltern Energy Group for your smart charger installation?
We do not ask you to fill in self-survey forms or upload your own photos. Every job starts with one of our engineers visiting your property in person. If your consumer unit needs attention, we tell you upfront before anything is agreed. After installation, we provide six months of aftercare. If anything stops working, we are local and back within days. Our NAPIT-registered engineers are certified to BS 7671 and all work is signed off with an installation certificate.
